Senior Launch Mechanical Engineer

About the Team: 

The Launch team operates at the intersection of every major aspect of Terran R from stages and payloads to ground systems launch landing and refurbishment. The Cape is the only place where you see it all come together offering a level of exposure and responsibility unmatched elsewhere in the program. This is where first flights happen where history is built on top of history and where the scale of what's underway is unlike anything in modern aerospace. The mission stays the same but the work evolves with every milestone: from first launch to reuse high-cadence operations and beyond. If you're looking to define what's next in space launch and write a new playbook not just repeat what’s already been done this is where it happens.

About the Role:

• Apply fundamental and practical engineering methods to develop innovative solutions
• Interpret and coordinate engineering requirements between vehicle and ground support teams
• Develop detailed 3D CAD models 2D drawings fluid system schematics and electrical schematics
• Conduct analyses of structural dynamic and system performance using hand calculations and finite element methods
• Present and communicate designs effectively to cross-functional teams and leadership focusing on methodology functionality and constructability

About You:

• Bachelor’s degree in Mechanical Engineering or a related field
• Minimum of 5 years of engineering experience in structural mechanism fluid power or other related field. 
  
• Proficiency with 3D CAD software (e.g. SolidWorks CATIA Creo)
• Working knowledge of mechanical design principles system integration and structural analysis
• Experience interpreting technical requirements and collaborating across engineering disciplines

Nice to haves but not required:  

• Designing manufacturing and testing launch vehicle interface mechanisms or tooling
• Familiarity with standards from NASA DoD Space Force or similar organizations
• Knowledge of structural materials and common manufacturing processes
• Experience with fluid system design including high-pressure gases cryogenics flammables or hydraulics
• Strong communication and documentation skills

What We Do

Relativity Space is on a mission to better connect humanity to space and the universe beyond our planet. Our medium-to-heavy lift reusable rocket Terran R will deliver customer payloads to orbit meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science exploration and innovation pioneering progress that reaches beyond the known.

Why Work With Us

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here you're not just executing tasks; you're solving problems that haven’t been solved before helping develop a rocket a factory and a business from the ground up.
